Removing HA

Removing
HA involves removing both software and hardware. Simply disabling the HA configuration
is insufficient and is only one part of the process. Because there is more
than one Screen that has the same IP address on the network, simply disabling
HA leaves two or more HA Screens on the network that are trying to route the
same traffic. This would disrupt the network traffic through the Screens.

You should remove the HA hosts one at a time to reduce the chances of
disrupting the network. If you remove the active HA host, you could lose some
connections. If you are removing a passive HA host, no connections will be
lost. You should, therefore, remove the passive HA host or hosts first to
avoid losing connections.

If you must remove the active HA host, find out if any connections may
be lost by running the following command on the active HA host that you want
to remove and on the passive HA host that will become the active HA host after
you remove the active HA host.

For local administration:

# ssadm lib/statetables

For remote administration:

# ssadm -r <Name_of_Screen> lib/statetables

If the statetables are in an acceptable level of synchronization, you
can proceed to remove the active HA host.
